XP & points
LuLinDingo gives your child points, called XP, for the work they do. XP is the running total of everything they have earned. It only ever goes up, so it works as a record of effort over time rather than a score that can be lost.
How XP is earned
Every correct answer is worth 10 XP. That is the same whether the question was easy or hard, and whether your child is just starting out or near the top of their age band.
When they finish a whole lesson, they get a bonus of 50 XP on top of the points from each answer. So a lesson with several correct answers plus the completion bonus adds up fast. Finishing is rewarded, not only getting individual questions right.
Is there a "level"?
No. There are no XP levels to climb, and the number does not unlock anything on its own. When the app talks about a "level," it means the starting point you pick during setup (the age band, or the result of the placement test), not a rank earned from points. XP itself is simply a total that keeps growing.
What moves your child forward through the lessons is completing them in order, not reaching an XP threshold.
Where the total shows
You will see the XP total in a couple of places. On your child's Progress screen it appears as "Total XP" next to their streak and hearts. In the grown-ups area it shows up again as "Total XP" alongside the other stats, so you can check progress at a glance.
A note on Dingo's Den
XP also acts as spendable acorns in Dingo's Den, where your child can buy decorations. Spending acorns never reduces their XP. The total stays whole, and buying things has no effect on lessons or progress. There is a separate article on the Den if you want the details.
